ELEVATOR.

, Specification of Letters Patent.

Patented Nov, 2*?, 191W.,

Application filed April 16, 1915. `Serial` No. 21,705.

To all whom t may concern.'

Be it known that I, MINNIE M. DENDIN- GER, a citizen of the UnitedStates residing at Louisville, in the county of Jefferson and State ofKentucky7 have invented a new and useful Elevator, of which thefollowing is a specification.

This invention has reference to elevators, and particularly to passengerelevators, and its object is to provide for the segregation ofpassengers desiring to go to different floors. In accordance with thepresent invention the elevatoris provided with partitions dividing itsinterior into an appropriate number of compartments, which extend to thefront of the elevator, and the doors at the dierent iioors protectingthe elevator shaft from access and permitting access to the elevatoritself are of such width or extent of travel as to give'admissionsimultaneously to all of the compartments.

Since it may be desirable at times to use only certain ones ofthe'compartnients or to enlarge a compartment by coalescing two or moreof such compartments into one, the partitions are so made and mountedthat they may be moved entirely out of the way car.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming a part of this specification, with the understanding,however, that while the drawings show a practical embodiment of theinvention, the latter is not confined to any strict conformity with suchshowing, but may be changed and modified so long as such changes andmodifications mark no material departure from the salientfeatures of theinvention.

In the drawings:

Figure 1 is a perspective view of the elevator car as seen from thefront. i

Fig. 2 is a front-to-rear vertical section of the elevator car taken atabout the mid point of the widthof the car.

Fig. 3 is a front elevation of the car and one type of door structurewhich may be employed.

Referring to the drawings, there is shown an elevator car 1, which sofar as its general structure is concerned may follow the usual lines,except that the carmay be made wider than customary to permit divisionof its inteiior into a suitable number of compartments to correspond tothe number of floors to whichthe elevator travels.

Secured within the car body at the rear portion thereof and near the topand bottom of the car body are beams 2, 3, respectively, these beamsbeing preferably of angle metal, each with one iiange arrangedhorizontally and directed toward the front of the car.

lIhe beam or bar 2 is located as near the bottom of the car as isconvenient oi` desirable, and the beam or bar 3 is for reasons whichwill presently appear spaced a short distance from the top of the car.

Each beam or bar 2 and 3 has perforations 4 and 5, respectively insuitable spaced relation and adapted to the perforations 4 and 5 arepintles 6 and 7 at respective ends of the rear end member 8 of apartition 9 made up of pivotally united strips l0 connected together inlazy-tong order to provide for expansion and collapse of the partition.No attempt is made to show the details of the construction of thecollapsible and extensible Vpartitions since any one of many well knownconstructions for this purpose may be used.

At the front edge of the partition is a front upright bar or member 11,as is customary in partitions of the general character illustrated. Atthe top and bottom ends of the front bar 11 are bolts 12, 13,respectively, adapted to engage in passages 14, 15 respectively in thebottom and top of the elevator car near the front thereof. Theperforations 4 and 5, and the perforations or passages 14 and 15 arecorrespondingly spaced with relation to the width of the car, so thatwith the pintles 6 and 7 engaging in the perforations 4 and 5 and thesliding members of the bolts 12 and 13 engaged in the perforations 14and 15, the interior of the car is divided by the partitions 9 into asuitable number of compartments. In the drawing four such compartmentsare shown, being defined by three partitions. On the upper portion ofthe car, or in other appropriate position with respect to the car aresuitable legends indicated at 16 to individualize the compartments toseparate iioors to which the elevator travels. F or instance, onecompartmentmay be reserved Vfor the first licor to which the elevatortravels, the next compartment may be reserved for the lill@ GOV secondfloor, and so on, the legends indicating theY particular floors forwhich the comn partments are reserved.

The partitions 9 are made so that when in the expanded position, theyreach from the rear to the front of the car, but these partitions may becollapsed so as to be shorter than when eXten'ded,and then may be movedabout the axis of the pintles 6 and 7 so as to lie flat against the backwall of the car, with the front member 11 between the hori- Zontal websof the bars 2 and 3, 4as illustrated in Fig. 1f.

In order to insert and remove the partitions, the rear upright 8 isshorter than the distance between the horizontal webs of the bars 2 and3 by a distance or amount somewhat greater than the length of the pintle6, wherefore the pintle 7, which is longer than the pintle 6, may beintroduced through the perforation 5, and the partition be liftedsufliciently tol permit the insertion of the pintle 6 in the perforation1, and when the end member is lowered to rest upon the bar 2, the pintle`7 is still within the perforation 5. When the partition is extendedtoward the front of the car, and the bolts 12 and 13 are moved to engagein the perforations 14 and 15, the partition is held in the extendedposition to form a division wall between the car. The bolts 12 and 13may be of any appropriate type whereby they become locked in theprojected position. On each lfloor the elevator shaft is provided with aclosure which in the particular' showing of the drawing is representedby doors 17, one or more of which may be employed, and in the particularshowing two such doors are illustrated in Fig.. 3 to facilitate theclosure. of so wide a door opening as some forms of cars equipped withthe present in-` vention would demand.

` The doors 17 `may be of the expansible and contractible type `similarto the partitions 9, and since such doors are in common use, it isunnecessary to describe them in detail. The doors 17 are to be taken astypical of any appropriate closure for the elevator openings.

, Then passengers desire to go to' some particular floor, they enter thecompartment, whereupon the elevator operator will know that suchpassengers desire to reach a certain floor without the necessity ofannouncement on the part of the passenger as to the floorv desired. Thevelevator conductor may be stationed in any one ofthe compartments, butwill usually be located in the compartment designated 1st Floor. Becauseof the open character of the partitions, the elevator conductor canreadily see across Copies of this patent may be obtained for the fullwidth of the elevator cargandmay ascertain for just what floors theelevator containspassengers, and therefore if there be no passengers inone or more of the compartments, it is unnecessary Yto stop at said ioorunless it be that some passenger desires to enter.

It will be understood, of course, that the legends 16 need notbe connedto the elevator car, butmay 'be placed elsewhere, the

purpose being to guide passengers tothe proper' compartments.

While the elevator the drawings Vas provided 4with three partitions, andthe perforations forthe attach mentof the apparatus to the car are ofsimilar number to thepartitions, it Ywill be understood that theperforations l and 5 in the bars 2 and 3 and the perforations 14 and 15may be of a greater VVnumber, than shown, or be otherwise arranged sothat the partitions may be equispaced or be irregularly spaced,'asmaybedesired. e

Vhat is claimed is: i Y v i 1. An elevator car provided with bars nearthe top and bottom at the rear, said bars having matching perforationstherein,

and the car also being provided` with like perforations near the front,and expansible and collapsible partitions provided with front and rearuprights with the rear uprights having pintles adapted to theperforations in the top and bottom, the rear'bars andthe front uprightsbeing provided with fastening means adapted to the perforations at thefront portion of the elevator car.

2. An elevator car provided with barsv at' the rear Vof the car beingrelated to per-V mit the attachment to, and removal of, the

rear uprights of the partitions from the perforations in the rear barsof the car.

In testimony, that Iv claimV the Vforegoing as my own I have heretoV`affixed my'signaT ture in the presence of two` witnesses.
